There are four categories of membership: Full, Allied Health, Trainee, and Honorary.

• Full Members are investigators in the broad field of intestinal transplantation with an interest in intestinal failure and transplantation who have contributed by their work to the advancement of knowledge in the field. A requirement of Full Membership is that the person must be a Member of the Association. Full Members are eligible to vote at the Business Meetings of the Association and to be an Officer or Councilor of the Association.


• Allied Health Members are persons who have an interest in intestinal failure and transplantation and who have contributed by their work to the advancement of knowledge in the field. Their status must be confirmed by their professional association card. Allied Heath Members have the same voting rights as a Full Member, but are ineligible to be an Officer or Councilor of the Association. They, however, have one standing representative on the Ad Hoc Council committee, and have a reduced membership fee.


• Trainee Members are persons with an interest in intestinal failure and transplantation who are in training positions (which must be confirmed by the signature of their supervisor). Trainee Members have no voting rights and are ineligible to be an Officer or Councilor of the Association.


• Honorary Members are proposed, seconded and elected by a majority vote of the voting Members of the Association via email or at a Business Meeting of the Association. Honorary Members are persons who have made major contributions to the field of intestinal transplantation, and need not necessarily be members of the Association. They have the rights of Full Members (including receipt of any official journals of the Association), but are not required to be members of the Association or to pay dues to the Association, and are not eligible for election as an Officer or Councilor.
